    摘要: Some embodiments provide a novel method for forwarding a packet at a managed switching element in a first domain. The method receives a packet from a local machine. The method encapsulates the packet with a first context identifier that identifies a first logical port of a first logical switching element that couples to machines in both the first domain and a second domain. The first logical port maps to a destination address of the packet. Based on a mapping of the first logical port to a second logical port of a second logical switching element that couples to machines in only the first domain, the method encapsulates the packet with a second context identifier that identifies the second logical port. The method transmits the twice-encapsulated packet out of a port of the managed switching element based on the second context identifier.

    摘要: A network control system that includes a first set of network controllers for (i) receiving a logical control plane definition of a logical switching element that couples to both a first set of network hosts in a first domain and a second set of network hosts in a second domain, (ii) translating the logical control plane definition of the logical switching element into a first set of flow entries in a first logical forwarding plane, and (iii) translating the first set of flow entries into a second set of flow entries in a second logical forwarding plane. The network control system includes a second set of network controllers in the first domain for (i) receiving a portion of the second set of flow entries and (ii) translating the portion of the second set of flow entries into a third set of flow entries in a physical control plane.

    摘要: Some embodiments provide a novel network control system for managing a set of switching elements in a network. The network control system includes a first set of network controllers for managing a first set of switching elements that enable communication between a first set of machines. The network control system includes a second set of network controllers for managing a second set of switching elements that enable communication between a second set of machines. The second set of switching elements is separate from the first set of switching elements and the second set of machines is separate from the first set of machines. The network control system includes a third set of network controllers for managing the first and second sets of network controllers in order to enable communication between machines in the first set of machines and machines in the second set of machines.
